I am playing minecraft on osx.  So, unfortunately, I cannot use the map rendering software that is available to windows users.

I got lost in a cave that was far away from my base.  When I finally came to the surface, I was totally lost.  I built a lighthouse and storage chest (to store 12 diamonds and coal and iron, etc) so I could potentially find it again and then after I went searching for my base again.  Well, I got killed and now have no idea where all the valuables I mined are now since I re spawned at home.

I wanted to see if someone one windows would be able to help render a map for me.  If so, should I just upload the save file?  Not sure what to do.

Any help would be appreciated!  Thanks
